Design of Front End Circuits for a Low Power Ultra Wide Band Receiver
by Shaker, Mohamed, Ph.D., University of Louisiana at Lafayette, 2015, 85; 3714137
Abstract (Summary)

Wireless devices in both office and home are playing a significant role in today’s communication system. The most known communication gadgets include cellular telephone and wireless local area network (WLAN) peripherals. Wireless connectivity products main target is to provide data access at any time but at the lowest possible data rate. In the last few years, the demand for higher data is increasing because the wireless devices became more popular. The fast development in wireless technology in recent years would initiate a new era of communication networks enabling data access everywhere at higher rates. The most challenging components at UWB PHY level are analog to digital converter and RF front ends since these circuit components need to perform in a broad range of frequency spectrum while consuming very little power and with little area overhead. Traditional design methodology practiced in the era of narrow band can’t meet the challenges of broadband system, thus new circuit topologies and design methodologies are needed. In this dissertation, a new radio frequency chain and low power analog-to-digital converters are proposed. The proposed converters process analog signals in a high range of frequencies with lower power consumption. The experimental results show significant improvement in the timing, throughput, and energy performances with a slight overhead in the circuit area.
